Why install a single flow VMC in your home in Luxembourg
Installing a single flow VMC is a simple and reliable way to ensure continuous renewal of indoor air. This device extracts stale air from humid rooms (kitchen, bathroom, WC) and promotes the entry of fresh air into living spaces through ventilation grilles.
Better indoor air quality
A single flow VMC eliminates pollutants and humidity present in the air. It prevents condensation on walls and prevents mold, thus improving quality of life and the durability of the building.
An economical and efficient solution
This system is economical both in purchase and maintenance. Its operation based on a simple air extractor allows for low energy consumption while ensuring constant and controlled air renewal.
A simple and adaptable installation
The single flow VMC can be installed in most homes, whether new or renovated. Thanks to its lightweight ducts and compact casing, it easily integrates into attics or a false ceiling without major work.
Optimized thermal comfort
By evacuating humidity and odors, the single flow VMC helps maintain a more pleasant indoor climate. It also prevents cold sensations related to excess humidity.

How a single flow VMC works
The operating principle is based on the mechanical extraction of stale air using a fan. Fresh air enters naturally through the grilles located in the joinery or walls, ensuring a balance between extraction and air intake.
Extraction of stale air
The extraction vents installed in humid rooms suck in polluted air. This air is then transported through ducts to the central unit before being expelled outside.
Fresh air intake
Air inlets are positioned in the main rooms. They allow filtered outside air to enter, promoting healthy air circulation and constant renewal.
Regulation and maintenance
Some VMCs have humidity sensors that automatically regulate the air flow. Periodic cleaning of the vents and the unit ensures optimal efficiency and better longevity of the system.
Regulations and standards for ventilation in Luxembourg
The installation of a single flow VMC must comply with the thermal and health requirements in force in Luxembourg. These rules aim to ensure sufficient air renewal while optimizing energy efficiency.
Ventilation standards
New or renovated homes must have a ventilation system that complies with national standards. These requirements ensure good indoor air quality and reduce heat loss.
Permits and authorizations
For a single-family home, no specific authorization is generally required, except in co-ownership or classified buildings. However, in a collective building, the installation may require prior approval from the co-ownership.
Maintenance and upkeep
Regular monitoring of the system is mandatory in collective housing to avoid malfunctions. Annual maintenance helps maintain constant efficiency and reduced electricity consumption.

Areas of the house affected by single flow ventilation
Single flow ventilation mainly acts in the humid areas of the house, but its impact is felt throughout the home. It helps balance the indoor climate and preserve building materials.
The kitchen
This is the room most exposed to steam and odors. The ventilation system effectively extracts grease and moisture released during cooking, thus limiting condensation marks and surface degradation.
The bathroom
The moisture released after a hot shower is quickly evacuated thanks to the extraction vent. This prevents the formation of mold on walls and ceilings and promotes faster drying of towels.
The toilets
The ventilation system allows for air renewal to avoid bad odors and maintain a healthy environment. The extraction vents are usually set to constant or timed flow according to needs.
The living spaces
Even if the ventilation system is not directly installed there, these rooms benefit from fresh air entering through the ventilation grilles. This creates a natural circulation of fresh air, improving the overall comfort of the home.
FAQ on installing single flow ventilation in Luxembourg
Is a professional required to install a single flow ventilation system?
Yes, hiring a professional ensures a compliant and secure installation. They size the system, install the ducts correctly, and ensure the right balance between extraction and air intake to avoid losses.
What is the difference between single flow and double flow ventilation?
Single flow ventilation extracts stale air without recovering heat, while double flow recovers heat from outgoing air. Single flow is more economical to purchase and easier to maintain for standard housing.
Can a single flow ventilation system be installed in an apartment?
Yes, but technical feasibility must be checked. In buildings, it is often necessary to obtain the agreement of the co-ownership and comply with air evacuation rules to avoid nuisances.
How to maintain a single flow ventilation system?
Simply clean the extraction vents and air intakes every 6 months. The unit should be dusted, and the filters checked regularly to ensure effective and lasting ventilation.
Does single flow ventilation consume a lot of electricity?
No, the consumption remains low, often below 50 kWh/year. The fan operates continuously, but its low-energy motor ensures limited energy costs.
